Description
Technical field
A kind of automobile chassis low-speed running device is the utility model is related to, controls achievable automobile chassis slow by the device
Speed walking and steering, applied to engineering machinery field.
Background technology
Traditional automobile chassis is main using there is friction wheel type or at a slow speed when applying man-hour requirement and reaching low speed walking function
Walking gear is box to realize this kind of function, and friction wheel type is to provide low-speed running power by rubbing wheel drive trailing wheel；Slowly
Box fast walking gear is to add a gear-box in drive shaft of rear wheel, in low-speed running is provided slowly by motor on gear-box
The power that speed walking needs；Two ways all needs people in driver's cabin control direction.
Utility model content
The technical problem to be solved by the utility model is to overcome technological deficiency existing in the prior art, there is provided a kind of vapour
Chassis low-speed running device, can make automobile chassis realize low-speed running mechanism, reach the control speed of travel, turn to, and advance
Or the function of the operation retreated.
The utility model proposes automobile chassis low-speed running device, including track rail assembly, turnover bracket；Track rail assembly leads to
Cross the front portion that turnover bracket is installed on automobile chassis.
Wherein, the track rail assembly includes the left crawler belt and right-hand track chiain being installed on track frame.
The left crawler belt and right-hand track chiain are driven by hydraulic motor by gear reducer.
Turnover bracket is made of stent, fixed frame and overturning oil cylinder.The middle part of stent and one end of fixed frame are hinged, fixed
The other end of frame is fixed on the front portion of automobile chassis.One end of stent is hinged a rotating seat, the other end and the overturning oil cylinder
Lever is hinged, and the cylinder seat of overturning oil cylinder is hinged on automobile chassis.
The track frame is installed on rotating seat by rotation axis.
The utility model device, simple in structure, action is safe and reliable, and speed of travel control is flexible.

Embodiment：
The utility model is further elaborated below in conjunction with attached drawing and specific implementation example.
As shown in Figure 1, 2, the automobile chassis low-speed running device, including track rail assembly 1, turnover bracket；Crawler belt is total
Into the front portion that automobile chassis is installed on by turnover bracket.
Turnover bracket is made of stent 6, fixed frame 8 and overturning oil cylinder 10.The middle part of stent 6 and one end of fixed frame pass through
Torsion shaft 7 forms hinged.The other end of fixed frame 8 is fixed on the front portion of automobile chassis.Rotating seat 4 by swing axis 5 with
Articulated manner is installed to one end of stent 6, and the other end of stent 6 and the lever of the overturning oil cylinder 10 pass through oil cylinder torsion shaft 9
Hinged, the cylinder seat of overturning oil cylinder 10 is hinged on automobile chassis.
The track rail assembly 1 includes the left crawler belt and right-hand track chiain being installed on track frame.The left crawler belt and right-hand track chiain by
Hydraulic motor is driven by gear reducer.Track frame 2 is installed on rotating seat 4 by rotation axis 3, and rotating seat 4 passes through swing
Axis 5 is installed to stent 6 and goes above.
Oil pump 11 is from chassis power takeoff power taking, for driving crawler travel and overturning oil cylinder.Valve 12 is used to control crawler belt row
Walk speed and direction and overturning oil cylinder extension and contraction control.
The utility model automobile chassis low-speed running device, by chassis power takeoff transfer tube, produces hydraulic system power
Output, by the control of valve 12, drives crawler travel direction and speed control, while drives the extension and contraction control of overturning oil cylinder, has
The low-speed running control mode of body is as follows：
1st, at a slow speed crawler belt land control device traveling：
Overturning oil cylinder 10 is shunk, and the torsion shaft that stent 6 is connected using fixed frame 8 is fulcrum, and stent 6 rotates counterclockwise, mechanism
Entire lowering, track rail assembly 1 land, and overturning oil cylinder 10 continues to shrink, chassis wheelie.By left and right crawler belt rotary speed,
Direction of rotation, so that control device advances, retreats, speed, turns to.
2nd, equipment is travelled using chassis：
Overturning oil cylinder 10 stretches out, and the torsion shaft that stent 6 is connected using fixed frame 8 is fulcrum, and stent 6 rotates clockwise, mechanism
Rise overally, track rail assembly 1 is liftoff, as shown in Fig. 2, equipment by chassis voluntarily.
