trailing arm trailer suspension-manufacture,factory,supplier from China

Adjusting arm, also called brake gap adjusting arm, the main function is to adjust the brake gap of the trailer axle brake.During the braking process of the vehicle, the brake components will continue to wear, the gap between the brake drum and the brake shoe will also increase to varying degrees, resulting in the formation of the pedal is too long, the brake chamber thrust is reduced, resulting in braking lag, braking force decline, wheel deviation, vehicle tail rejection and even brake failure and other problems.In order to ensure driving safety, maintain the stability of brake pedal travel

Brake system is a whole system, brake pump, self-adjusting arm, camshaft, brake, brake drum and a series of parts depend on each other and influence each other.

Large trucks refer to large vehicles used for transporting large amounts of goods, including the following types:1. Truck mounted trucks: These vehicles typically have a foldable crane arm installed at the front of the truck to lift and dump cargo from the truck. They are mainly used in construction, mining, and other industries that require a large amount of transportation and dumping of goods.2. Tractor trailers: This is a common type of freight vehicle consisting of a tractor and one or more trailers.

Generally speaking, the trailer axle is mainly composed of the shaft body, camshaft assembly, brake assembly, shaft end assembly and cotter pin, adjusting arm, various washers, nuts and bolts.1. Total axial bodyIt mainly includes axle body, brake bottom plate, spherical bearing seat, air chamber seat, etc., which is located in the central position of the axle and connects the two sides of the wheel ends.

The suspension of semi-trailer is an important part that connects the travelling device of semi-trailer chassis with the frame. The vehicle's support force, braking force, driving force, etc., are transmitted through the suspension system, and can also reduce the impact of the bad road on the vehicle - shock absorption, to ensure the stability of the vehicle, its importance is self-evident.

Under normal circumstances, the suspension of the semi-trailer can be mainly divided into four types:1, rigid suspension.The chassis of the rigid suspension directly acts on the axles between the wheels, without a spring as a buffer, and completely relies on the swing of the balance beam to maintain the relative balance of the front and rear axles when the road is uneven.This kind of suspension is relatively rare at present, because its shock absorption effect is very poor, mainly used in low-speed cargo carrying low-plate semi-trailer.2.

Trailer suspension is an important component connecting trailer frame and trailer axle, which is used to transmit the force and torque between the wheel and frame, cushion the impact force from the uneven road surface to the frame or body, reduce the vibration caused by it, so as to ensure that the car can run smoothly.Suspension can generally be divided into independent suspension and non-independent suspension two, usually the trailer is used by non-independent suspension. Common non-independent suspension can be divided into the following four types:1.

Trailer axle is a typical support bridge, composed of axle beam, camshaft, brake assembly, wheel end assembly, adjusting arm and various types of washers, bolts, etc., the main role is to bear the weight of the body. In addition to load, it can also play a role in assisting vehicle braking, maintaining vehicle driving, slowing down bumps, etc., without steering and driving functions.From the perspective of vehicle structure, the axle belongs to a part of the vehicle chassis and belongs to the driving system.

The suspension system is of great significance to the driving and safety performance of the vehicle.

To say which trailer suspension in the industry has received the most attention, I am afraid it is the air suspension.Since January 2020, air suspension has been forced to be installed on all three-axis grid and three-axis fence plate semi-trailers in the domestic market, which has greatly increased the application rate of air suspension on semi-trailers.Compared with the traditional steel plate suspension, the advantages of air suspension are relatively obvious:1. Lighter self weight.
