にそのパーキングブレーキ装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a traveling unit of a hydraulic crawler type vehicle, and particularly to a parking brake device thereof.

〔従来の技術〕[Conventional technology]

レーキ力を解除する。As shown in FIG. 3, the parking brake device of the hydraulic crawler type vehicle traveling unit is built in the hydraulic motor 02, and a plurality of friction plate wheels 15 and receiving wheels 16 are alternately stacked.
A spring force is applied to one end surface of the brake release piston 17 to generate a braking force. Conversely, hydraulic pressure is applied to the brake release piston 17 to push up the spring force and release the brake force.

カバー014の内面より突出す形状となっている。In this way, the parking brake device has the same structure as the multi-plate clutch. However, since the disc spring 18 that can generate a large force with a small stroke is used as the spring, the cylindrical portion 14a supporting the inner diameter of the disc spring 18 is fixed to the side surface of the fixed casing 11 in order to prevent the disc spring in the radial direction. The shape is such that it projects from the inner surface of the motor cover 014.

筒部14aをモータカバー014の内面に形成する必要があ
る。According to the conventional technique as described above, as the radial positioning member of the disc spring 18, it is necessary to form the cylindrical portion 14a for regulating the inner diameter position of the disc spring on the inner surface of the motor cover 014.

従って、円筒部14aの高さだけ油圧モータ02の長さが
長くなり、またモータカバー014の形状が複雑になる等
の問題点を有する。Therefore, there are problems that the hydraulic motor 02 becomes longer by the height of the cylindrical portion 14a, and the shape of the motor cover 014 becomes complicated.

〔課題点を解決するための手段〕[Means for Solving Problems]

皿バネ内周をモータ内部品のバルブプレート外周で支

皿バネ支持用円筒部を廃止する。The disc spring has a structure in which the inner periphery of the disc spring is supported by the outer periphery of the valve plate of the motor internal component, and the disc spring supporting cylindrical portion conventionally provided on the inner surface of the motor cover is eliminated.

The traveling unit 1 is fixed to the vehicle fixing frame 6 with bolts 10, the sprocket 8 for driving the crawler shoe 7 is fixed to the rotary casing 12 with bolts 9, and the tooth portion 8 is engaged with the crawler shoe 7. The rotating casing 12 is supported by two bearings 13 on a fixed casing 11 having the hydraulic motor 2 and the parking brake 3 built therein, and is rotatable around the fixed casing 11. The rotary casing 12 serves as an output end of the speed reducer 4 that reduces the rotational speed of the hydraulic motor 2.
