Abstract

The invention belongs to the field of agricultural mechanical equipment, and discloses a tractor brake device and a tractor with the tractor brake device. The tractor brake device and the tractor with the tractor brake device solve the problem of unevenness in abrasion of a brake pad of an existing tractor brake device. The brake device comprises a hub, two arc brake pads and a shifting mechanism, the hub comprises a bottom wall and side walls, the brake pads are oppositely arranged in the hub, the lower ends of the brake pads are hinged to the bottom wall of the hub, or an elastic device is abutted against between the lower ends of the brake pads. The shifting mechanism comprises a rotary block and a convex shaft, the convex shaft is fixed to the middle of the rotary block and extends downward, the bottom wall between the upper ends of the two brake pads is provided with an elongated hole extending bilaterally, and the convex shaft is embedded into the elongated hole. Using the brake device enables the two brake pads to be abraded uniformly, and the service life of the brake device is prolonged.

Description

technical field [0001] The invention relates to a component and equipment of an agricultural machine, in particular to a brake device of a tractor and the tractor. Background technique [0002] The brake device is a very important part on the tractor. see figure 1 , the existing brake device generally includes two arc-shaped brake pads 2 and a wheel hub 1 . The brake pad 2 is relatively arranged in the hub 1 , its lower end is hinged on the surface of the hub 1 , and its upper end is opposite to the upper end of another brake pad 2 . A toggle mechanism is provided between the upper ends of the two brake pads 2. When braking, the toggle mechanism can be controlled to push the brake pads 2 to the side of the hub 1, so that the brake pads 2 and the side of the hub 1 are in contact with each other. To slow down and achieve the purpose of braking. [0003] Existing toggle mechanism generally has two kinds of hydraulic type and mechanical type, and the hydraulic type toggle me...
