rear leaf spring-manufacture,factory,supplier from China

Leaf spring is one of the most widely used elastic components of automobile suspension, also known as leaf spring, composed of a number of pieces of equal width and unequal length alloy spring, generally presents a symmetrical section structure, the thickness of each spring can be the same or different.Compared with other types of elastic components, the leaf spring structure is simple, low cost and maintenance costs, strong rigidity, load-bearing, not only can play the role of shock buffering, but also has the function of guidance, transmission of force and torque in all directions, but also

Suspension is a connection device between the axle and the frame, which is used to transmit force and torque, reduce the impact of the road surface on the body, reduce the body vibration caused by the road surface fluctuation, and ensure the smooth running of the vehicle.Although the spring suspension is not as good as the air suspension in terms of shock absorption performance and self-weight, it has simple structure, low cost and maintenance cost, strong rigidity and high load-bearing force.Moreover, the leaf spring has a guiding function, can transmit the force and torque in all directions,

The trailer rear axle generally refers to the trailer axle installed on the semi-trailer. It is connected to the frame through the suspension, and the wheels are installed at both ends without driving and steering functions. action.Some car owners believe that compared with the steering axle and drive axle, the function of the rear axle of the trailer is relatively single, the structure is relatively simple, more durable, and more resistant to construction, so it is still used after the rear axle fails.

Vehicle lightweight is one of the popular keywords in the automotive industry in recent years. It not only helps to save energy and reduce emissions, conforms to the trend of environmental protection, but also brings many benefits to car owners, such as more loading capacity, less fuel consumption, better handling, and higher comfort.In order to pursue lightweight, the industry can be said to have hollowed out ideas, from car bodies, beams, upper fittings, to axles, tires, leaf springs, etc., all are studying how to obtain lighter self weight.

Suspension is a connection device between the axle and the frame, which is used to transmit force and torque, reduce the impact of the road surface on the body, reduce the body vibration caused by the road surface fluctuation, and ensure the smooth running of the vehicle.At present, the common suspensions in the commercial vehicle market are mainly leaf spring suspension and air suspension. Although the call for air suspension has become more and more popular in recent years, it is still difficult to shake the market application rate of 80% of leaf spring suspension.

Trailer axle is a typical support bridge, the main role is load-bearing, used to bear the weight of the body, and then can ease road bumps, ensure vehicle braking, maintain vehicle driving, etc., does not have steering or driving function.From the braking mode, the rear axle of semi-trailer can be divided into two types: disc type and drum type.

Wheelbase refers to the straight-line distance between two adjacent wheels on the same side of the car, generally the distance from the center of the front axle to the center of the rear axle. Semi-trailer wheelbase is the distance between the front and rear axle of the semi-trailer.Wheelbase is a very important parameter of semi-trailer, which determines the center of gravity position and space of semi-trailer, and is closely related to the performance of semi-trailer.

Trailer lightweight is one of the more popular words in the industry, and it is also an important trend in the development of vehicles.

The rear axle is one of the key load-bearing components on the semi-trailer, and it is also closely related to the braking performance of the vehicle. In general, the wheel end components of trailer axles of different tonnages are also different. But in practical applications, we often hear that "13t axles are converted to 16t brakes", how to understand this?In fact, the so-called "refitting 13t axles with 16t brakes" refers to refitting the original brakes on the rear axle of a 13t semi-trailer into specifications for 16t axles.

Aluminum alloy semi-trailer refers to the carriage, side protection, rear protection, traction seat plate, suspension, hinges, roof rod, etc. are all made of aluminum alloy material, instead of the traditional steel structure.
