Problems solved by technology

[0003] The driving road surface of dual-purpose traction locomotives for rail and road is often bumpy, multi-slope, slippery, oily, rainy and snowy, and many bends, etc., and the working environment is relatively harsh. When driving on the above-mentioned roads, slipping, being trapped and unable to pass obstacles, and poor climbing ability often occur; in addition, the contact friction area between the two-wheel drive or four-wheel drive dual-purpose tractor and the road / rail is small, and the friction force is small. The ability cannot be fully utilized, which is not conducive to the improvement of traction ability
[0004] In order to solve the above problems, some enterprises have developed rail-road dual-purpose eight-wheel drive traction locomotives. However, due to the large distance between the front and rear axles of the eight-wheel drive traction locomotives, the turning radius is large when turning on the road, and the maneuverability becomes poor.

Abstract

The invention belongs to the technical field of rail-road dual-purpose traction locomotives, and particularly relates to a rail-road dual-purpose eight-wheel-drive traction locomotive floating axle device and a using method thereof. A front frame of an eight-wheel-drive traction locomotive is provided with two pairs of driving wheels, the two pairs of driving wheels are the first front wheel and the second front wheel correspondingly, and the first front wheel is arranged between a guide wheel and the second front wheel; the floating axle device is a lifting device for a drive axle of the first front wheel and comprises a fixing plate, a lifting arm and a hydraulic cylinder. The rail-road dual-purpose eight-wheel-drive traction locomotive floating axle device has the advantages that the eight-wheel-drive traction locomotive for the rails and the roads gives full play to the advantages that the traction locomotive has high traction force on the steel rails, has high trafficability on wet and slippery / rugged roads and still has considerable maneuverability when running on the roads, the advantages are improved, disadvantages are avoided, and traction requirements are better met.

Description

technical field [0001] The patent of the present invention belongs to the technical field of dual-purpose traction locomotives for rail and road, and specifically relates to a floating bridge device for a dual-purpose eight-drive traction locomotive for rail and road and a method for using it.
