Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Such as image 3 As shown, the vehicle frame includes traction hanging ring 1a, rear guide hole 1b, vehicle frame main body 1c, front guide hole 1d, front oil cylinder seat 1e, rear oil cylinder seat 1g and other parts. The traction link 1a is connected to the traction rod, traction rope, etc., and the traction force is output here; the frame body 1c is welded by rectangular steel pipe and channel steel; the rear guide hole 1b and the front guide hole 1d are arranged at the front and rear ends of the frame body. The guide column of the driving state conversion device passes through this; the front oil cylinder seat 1e and the rear oil cylinder seat 1g are used for the oil cylinder of the driving state conversion device to connect with the vehicle frame 1 .

Abstract

The invention provides a multifunctional chassis of a track tractor. The multifunctional chassis comprises a frame, a track traveling mechanism and a road traveling mechanism, wherein the track traveling mechanism comprises a balance-beam walking mechanism at the front end and track driving mechanisms at the two sides of the rear end, wherein the balance-beam walking mechanism is mounted at the bottom of the frame through support shafts and support shaft seats, which are located at the middle of a balance beam, and the track driving mechanisms are respectively mounted at the two sides of the bottom of the rear end of the frame; the road traveling mechanism comprises a steering axle at the front end and a road driving mechanism at the rear end, wherein both the steering axle and the road driving mechanism are mounted on the frame through traveling state switching devices; the track driving mechanisms comprise hydraulic motors, bearing mounting seats, rear track wheels, a track wheel axle and a pair of tapered roller bearings, wherein the track wheel axle is fixedly arranged in the bearing mounting seats through the tapered roller bearings which are mounted in a face-to-face manner, the rear track wheels are mounted on extending ends of the track wheel axle, input ends of the track wheel axle are connected with output shafts of the hydraulic motors, the hydraulic motors are mounted on end faces of the bearing mounting seats through flange faces, and the track driving mechanisms are connected to the frame through the bearing mounting seats.

Description

technical field [0001] The invention relates to a multifunctional chassis of a rail tractor, which has two sets of independent driving mechanisms for the road surface and the track and a driving state conversion device, and can be applied to low-speed and heavy-load tractors and transport vehicles with two driving conditions on the track and the road. It is used in caverns, mines, workshops and other occasions. Background technique [0002] At present, domestic rail tractors only have the function of running on the track and cannot drive off the track. Road tractors can only run on the road without the function of running on the track. However, the chassis of these two vehicles has a single function, and they are suitable for both road and track vehicles. Not applicable where required by the conditions. Another domestic road-rail dual-purpose vehicle adopts a plan to add a set of guide wheels on the basis of the road vehicle running system. When driving on the road, the gui...
