Description

Technical Field

[0001] This utility model relates to the field of vehicle braking system technology, and in particular to a vehicle parking brake control mechanism and a tractor. Background Technology

[0002] The braking system is a crucial component of a tractor, used to stop the tractor on slopes and decelerate it while driving. Braking performance is a vital safety indicator within the tractor's overall performance system, affecting not only the tractor's power output but also directly impacting the safety of the driver and the vehicle. This is especially true in hilly and mountainous regions with their varied terrain and complex topography, which places even higher demands on the braking performance of machinery operating in these areas.

[0003] In conventional tractors, the service brake and parking brake are usually linked. In this structure, the service brake does not affect the parking brake when it is working. However, the parking brake is connected to the brake pedal shaft by a lever, which controls the brake. When the brake pedal shaft rotates, it will cause the service brake pedal to rotate as well. The parking brake cannot be operated independently. In extreme cases where the service brake fails, it will affect the parking brake. Utility Model Content

When the brake pedal is depressed, the parking brake is unaffected by the long-hole connecting fork between the parking brake lever and the first brake arm; when the parking brake handbrake handle is raised, the service brake is unaffected by the long-hole connecting fork between the brake pedal assembly and the first brake arm. This achieves independent braking for the parking brake and service brake, ensuring vehicle braking even in extreme situations where the service brake fails. Braking is convenient, with an independent handbrake. The structure is simple and the cost is low.

[0013] Furthermore, the parking brake lever is welded onto the parking brake mounting bracket.

[0014] The beneficial effect of adopting the above-mentioned further technical solution is that the welding of the parking brake mounting bracket provides stable support for the parking brake lever, which facilitates the stable movement of the parking brake lever.
