Embodiment 1

[0028] refer to figure 2 , image 3 and Figure 4 , In this embodiment, the wheel 4 includes a left wheel end cap and a right wheel end cap. The left wheel cover and the right wheel cover are respectively rotatably connected to the wheel axle 42 through bearings. Both ends of the wheel axle 42 respectively protrude from the two wheel end covers 41 and extend outward. The spacer 1 is installed on the left wheel end cap, and certainly can also be installed on the right wheel end cap. The limiting member 1 is provided with a through hole for the wheel axle 42 to pass through. The limiter 1 is ring-shaped, and the ring-shaped limiter 1 is placed on the wheel axle 42 and fixedly connected to the left wheel end cover through fasteners. The fastener is a screw. The limiting body 2 is also provided with a through hole for the wheel axle 42 to pass through. The limiting body 2 is sleeved on the wheel axle 42 and located outside the limiting member 1 . The limiting body 2 is ar...

Embodiment 2

[0036] refer to Figure 9 and Figure 10 The difference between the second embodiment and the first embodiment is that the limiting member and the wheel cover 41 are integrally formed, and the limiting body 8 and the pushing device 9 of the parking brake device are installed on the vehicle frame 10 .

[0037] In this embodiment, the wheel cover 41 is provided with a plurality of limiting holes 45 surrounding the periphery of the wheel shaft 42 , and the plurality of limiting holes 45 take the axis of the wheel shaft 42 as a circle center. The wheel cover 42 provided with a plurality of limiting holes 45 constitutes a limiting member engaged with the limiting body 8 . Of course, in other embodiments, the limiting member can also be an annular plate, and a plurality of limiting holes 45 are provided on the annular plate, and the limiting member is used to be fixedly connected to the wheel end cover 41 . The wheel axle 42 is fixedly connected to the vehicle frame 10 to install ...

Abstract

The invention discloses a parking brake device, which comprises a limiting member fixed on wheels, a limiting body capable of being engaged with or disengaged from the limiting member, and a pushing device for driving the limiting body to be engaged with or disengaged from the limiting member. The limiting member of the parking brake device provided by the invention is connected to a wheel end cover, and the pushing device drives the limiting body to be engaged with or disengaged from the limiting member, wherein when the limiting body is engaged with the limiting member, the displacement of the wheel end cover is restricted for limiting the rotation of the wheels; when the limiting body is disengaged from the limiting member, the restriction on the wheel end cover is released and the wheels are free to rotate. The structure is simple and the operation is easy.

Description

technical field [0001] The invention relates to the technical field of parking brakes, in particular to a parking brake device installed on wheels. Background technique [0002] The existing vehicle restricts the movement of the vehicle by manipulating the hand brake after parking, prevents the vehicle from slipping, and improves the parking safety of the vehicle. However, the control method of the handbrake is relatively cumbersome and requires a lot of physical strength. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a parking brake device that is convenient to handle. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a parking brake device, including a limiter for fixing on the wheel, a limiter that can be engaged with or separated from the limiter, and a The pushing device for engaging or separating the limiting body and the limiting ...
