Problems solved by technology

This kind of parking brake structure is relatively simple, but because the operating mechanism is close to the brake pedal, it is far away from the seat and the position is lower, and it is not in the comfort zone of human body operation, so the operation is relatively inconvenient and easy to cause fatigue; and if the driving brake If the control mechanism fails, the parking brake will not work at the same time, and the braking safety cannot be well guaranteed.

Embodiment Construction

[0022] For ease of understanding, the technical solutions of the present invention are further specifically described below in conjunction with the accompanying drawings and through embodiments:

[0023] Such as figure 1 and figure 2 As shown, a small and medium-sized wheeled tractor braking device includes a brake handle 1, a brake cable 2, a brake 3, a rocker arm return spring 4, a brake rocker arm 5, a pull rod 6, a foot brake rocker arm 7, Brake pedal 8, pull-up rod 9 and pedal return spring 10.

[0024] The brake pedal 8 is fixed to the inside of the driver's compartment through the brake pedal fixing shaft 17, and the brake pedal 8 can freely rotate around the brake pedal fixing shaft 17.

[0025] The upper right side of the brake pedal 8 is provided with an upper tie rod connecting plate 18 .

[0026] The upper end of the brake pedal 8 is provided with a pedal return spring 10. After the driver's foot leaves the brake pedal 8, under the active force of the pedal ret...

Abstract

The invention relates to a small and midsize wheeled tractor braking device. The small and midsize wheeled tractor braking device comprises brake handles, a brake pull wire, a brake, a rocker arm return spring, a brake rocker arm, a low pull rod, a foot brake rocker arm, brake pedals, and an upper pull rod, wherein the rocker arm return spring is arranged at the lower end of the brake, and is connected with the brake rocker arm; the upper end of the upper pull rod is rotatably connected to the upper part of the brake pedals, and the lower end of the upper pull rod is connected with the foot brake rocker arm; a pedal return spring is arranged at the upper ends of the brake pedals; a lower arm of the foot brake rocker arm is arranged at one end of the lower pull rod, and a lower pull rod connecting fork is arranged at the other end of the lower pull rod; the lower pull rod connecting fork is connected with a lower arm of the brake rocker arm, and the brake pull wire is arranged under the brake handles. A brake pull wire connecting fork is arranged at the lower end of the brake pull wire, and is connected with the upper arm of the brake rocker arm; a slotted hole is formed in the connecting part of the lower pull rod connecting fork / brake pull wire connecting fork and the brake rocker arm. According to the small and midsize wheeled tractor braking device disclosed by the invention, good parking safety is guaranteed, and the operation and control comfortability is improved.

Description

technical field [0001] The invention belongs to the technical field of brake devices, and in particular relates to a brake device for a small and medium-sized wheeled tractor. Background technique [0002] The working conditions of the tractor are relatively complicated, and it may be necessary to brake and stop at any time during driving or operation. Because the road or field conditions are usually bad, it is necessary to perform parking brake after parking to avoid economic loss or personal injury caused by rolling. . At present, the parking brake method of small and medium-sized wheeled tractors is mainly an auxiliary form, that is, a limit mechanism is set near the service brake pedal, and the driver depresses the brake pedal while manipulating the limit handle to the corresponding position to fix the brake. Pedal, so as to realize the parking brake effect. This kind of parking brake structure is relatively simple, but because the operating mechanism is close to the b...
