Problems solved by technology

In the tram (light rail) with the above structure, the two wheels are directly connected by an axle, so that the driving force of the vehicle is directly transmitted to the wheels through this axle, resulting in a higher floor from the ground in the car, and it takes several steps to get there. In the car, getting on and off is inconvenient

Abstract

A low-floor rail (light rail) trolley-bus with an U-shaped structure frame, which comprises automobile body, U-shaped frame and air spring. The air spring is located on the U-shaped car shelf, and the automobile body is installed on the air spring; the U-shaped frame includes wheel, speed-change gear, axletree, and wheel is linked with the speed-change gear to made the frame be U-shaped, vehicle traveling power transmits to the wheel by the change gear installed around the wheel. The design of this device is scientific, process is simple, which is convenient for manufacture, the U-shaped car frame is employed without steering shelf, two shafts are connected with the automobile body through the air spring, wheel is linked with the speed-change gear to made the frame be U-shaped, the vehicle traveling power transmits to the wheel by the change gear installed around the wheel, which realizes 100 percent of low-floor structure for passenger area.

Description

Technical field: [0001] The invention relates to a low-floor rail (light rail) electric car with a U-shaped frame without a bogie. Background technique: [0002] At present, common rail (light rail) trams adopt four-wheel and eight-wheel bogie body structures with spindles, and the wheel sets are divided into driving wheel sets and driven wheel sets. There is no reducer for the driven wheel pair; the axle bearing box and the frame beam are positioned by angle rubber springs; There are oil discharge holes and oil level inspection holes; the car body is connected to the bogie through the bolster beam, which bears the load of the car body, transmits traction force and braking force, and has a guiding function when turning in a curve. The center part of the bolster beam is a cone The body press-fitted bush is matched with the mandrel on the car body. There are longitudinal and transverse limit stops on both sides of the bolster beam. The vertical load passes through the spheric...
