Electric pallet truck with adjustable axle distance

Abstract

The invention discloses an adjustable wheelbase type electric transport vehicle, comprising a load frame, a front end of the load frame is provided with a head, a rear bridge frame is arranged below the load frame, a traveling wheel is installed on the rear bridge frame, and the travel wheel is connected with a Walking drive device, two rear axle slideways are symmetrically arranged on the carrier, and rear axle sliders are arranged in the two rear axle slideways. A rear axle support beam is fixedly connected between the two rear axle sliders, and the rear axle support beam is The rear bridge frame is fixedly connected; the rear bridge frame is provided with a distance-adjusting worm along the front and rear directions of the carrier, and a distance-adjusting worm wheel corresponding to the distance-adjusting worm is fixed on the rear axle support beam, and the distance-adjusting worm is connected with a distance-adjusting drive device; In the present invention, the rear bridge frame and the load frame are set to be slidingly connected, and the front and rear positions of the rear bridge frame are adjusted through the worm gear transmission, so as to achieve the purpose of adjusting the wheelbase, so that the center of gravity of the present invention is always kept between the traveling wheel and the steering wheel when carrying goods. It can effectively prevent the occurrence of back flipping.

Description

technical field [0001] The invention relates to the technical field of electric transport vehicles, in particular to an adjustable wheelbase electric transport vehicle. Background technique [0002] Electric pallet trucks are logistics handling equipment powered by batteries and driven by motors. Because of their labor-saving, high efficiency, stable cargo operation, simple operation, safety and reliability, low noise, and no pollution, they are widely used. Factory areas, logistics parks, greenhouse operations and other fields. [0003] The structure of the electric pallet truck usually includes a carrier at the rear and a steering handle head in the front. A rear bridge is fixedly installed under the carrier. Traveling wheels, driving motors, etc. are installed on the rear bridge. steering wheel. Because the distance between the rear axle frame and the front of the vehicle is fixed, the wheelbase of the road wheels and steering wheels is fixed. The rear end of the load ...

AI Technical Summary

Problems solved by technology

Because the distance between the rear axle frame and the front of the vehicle is fixed, the wheelbase of the road wheels and steering wheels is fixed. The rear end of the load rack is lengthened, so that after the electric pallet truck is loaded, the center of gravity of the whole vehicle will shift backwards, which will easily cause the electric pallet truck to turn backwards, causing the goods to fall and affect the normal work
