Abstract
The utility model discloses a hydraulic motor driving device for a hub, which comprises the hub and a hydraulic motor, wherein the hydraulic motor is arranged in the hub; the inner cylinder body of the hydraulic motor serves as a stator; the outer casing of the hydraulic motor serves as a rotor; the outer casing and the hub are fixedly connected through bolts or are directly processed into a whole; and the hub is directly driven to rotate by the rotation of the outer casing of the hydraulic motor. The hub hydraulic motor driving device has a simple and compact structure and fully releases the space around the hub.
Description
Technical field
The utility model relates to a kind of hub drive device, particularly a kind of wheel hub driving device for hydraulic motor.
Background technology
Than the machine driven system of orthodox car, the fluid motor-driven system has advantages of that volume is little, lightweight, response rapidly, large, the space flexible arrangement of stable drive, driving torque.Usually, in the fluid motor-driven system, the body skin of HM Hydraulic Motor is as stator, and inner cylinder body is as rotor.Hydraulic motor arrangement is in the wheel nave side, and the rotation by output shaft comes drive hub to rotate.The output shaft of HM Hydraulic Motor directly or by intermediate reduction gear mechanism is connected with wheel hub.Application number is the utility model patent of CN201120467519.2, and described is a kind of auxiliary hydraulic motor driving device, comprises drive hub and HM Hydraulic Motor, and drive hub is connected with semiaxis, and this semiaxis is directly captiveed joint with the S. A. of HM Hydraulic Motor.But this HM Hydraulic Motor is placed in the wheel nave side, inner cylinder body is as rotor, and still there is complex structure in the actuating device that the rotation by hydraulic motor output shaft comes drive hub to rotate, the shortcoming that near the space wheel hub does not obtain discharging fully.
Summary of the invention
The utility model technical issues that need to address are for general wheel nave side that HM Hydraulic Motor is placed in, inner cylinder body is as rotor, rotation by hydraulic motor output shaft comes the actuating device of drive hub rotation to have complex structure, the shortcoming that near wheel hub space does not obtain discharging fully proposes a kind of wheel hub driving device for hydraulic motor.
For addressing the above problem, technical solution adopted in the utility model is: a kind of wheel hub driving device for hydraulic motor comprises wheel hub and HM Hydraulic Motor.Hydraulic motor arrangement is in wheel hub, and its inner cylinder body is as stator, and body skin is as rotor, and body skin and wheel hub are bolted to connection, and perhaps directly are processed into one with wheel hub, rotates by the direct drive hub of the rotation of hydraulic motor shell body.
Adopt the beneficial effect that technique scheme produces to be: wheel hub driving device for hydraulic motor described in the utility model with hydraulic motor arrangement in wheel hub, rotate by the direct drive hub of the rotation of its body skin, simple in structure, compact, fully discharged near the space wheel hub.
Description of drawings
Fig. 1 is the structural representation of wheel hub driving device for hydraulic motor described in the utility model.
Fig. 2 is the inner structure schematic diagram after wheel hub driving device for hydraulic motor described in the utility model is dissected.
In figure: the 1-wheel hub; The 2-HM Hydraulic Motor; The 3-body skin; The 4-inner cylinder body
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Described in the utility model is a kind of wheel hub driving device for hydraulic motor, comprises wheel hub 1 and HM Hydraulic Motor 2.What HM Hydraulic Motor 2 adopted is the ball-and-spigot hydraulic motor with inner curved piston, can transmit larger torque, does not need speed reduction gearing to get final product direct drive hub 1.HM Hydraulic Motor 2 is installed in wheel hub 1, and the inner cylinder body 4 of HM Hydraulic Motor 2 is as stator, and body skin 3 is as rotor, and body skin 3 is bolted to connection with wheel hub 1, perhaps directly is processed into one with wheel hub 1.In hydraulic oil input hydraulic pressure motor 2, make body skin 3 rotations of HM Hydraulic Motor 2, the rotation of hydraulic motor shell body 3 directly drives wheel hub 1 and rotates, i.e. vehicle wheel rotation.
