Rubber tire low-floor bogie
A technology of rubber tires and bogies, which is applied in the direction of bogies, devices for lateral relative movement between the chassis and the bogies, and railway car body parts, etc., which can solve the problem of unguaranteed traffic speed in urban areas and the streamline performance of vehicles. Poor quality, long body and other problems, achieve the effect of saving space, reducing the height of the car body, and maintaining the balance of the car body

Embodiment
[0025] as attached Figure 1-2 A low-floor bogie with rubber tires shown includes an independent wheel set 1, a frame 2, two motor gearbox transmission devices 3, a secondary suspension device, and a traction device. The frame 2 consists of two side beams, two Composed of beams and two end beams; the motor gear box transmission device 3 is installed in the middle of the frame 2 side beams, including the motor and the gear box, the motor and the gear box are designed as one, and the motor is arranged horizontally, and the gearbox is vertical It is arranged to output to both ends at the same time, so that the wheelbase of the bogie can be shortened, the weight of the bogie is lighter, and the curve passing performance is better; a motor gearbox transmission device 3 is connected to the motor gearbox transmission device through two universal joints 4 respectively. Two reversing transmission gearboxes 1-4 on the same side of device 3. The independent wheel set 1 (as attached Fi...

The invention relates to a rubber tire low-floor bogie. The rubber tire low-floor bogie comprises independent wheel pairs, a framework, motor gearbox transmission devices, a secondary suspension device and a draft gear. The framework is composed of two side beams, two cross beams and two end beams. The independent wheel pairs comprise four rubber tires and four turning transmission gearboxes. Each rubber tire is provided with one turning transmission gearbox. The motor gearbox transmission devices are installed on the middle portions of the side beams of the framework and comprise motors and gearboxes. The motors and the gearboxes are designed to be integrated. The motors are transversely arranged, the gearboxes are longitudinally arranged, and the gearboxes conduct output to the two ends simultaneously. Each motor gearbox transmission device is connected with the two turning transmission gearboxes located on the same side of the motor gearbox transmission device through two universal joints. Thus, a rail vehicle can run on the rail-free road surface, and the vehicle with the bogie can fully achieve low-floor and high-streamline performance.
Description
technical field [0001] The invention relates to a novel bogie for urban public transport vehicles, in particular to a low-floor bogie with rubber tires. Background technique [0002] Traditional rail vehicles (such as modern trams) have the advantages of large vehicle marshalling yard, low noise by electric traction, no exhaust emissions, low entrance and easy to get on and off, etc. It is a popular urban public transport vehicle, but The bogies used in it all use steel wheels and need to run on specially laid steel rails. However, the laying of steel rails will bring about higher costs and damage to the road surface. Therefore, trams can only be used in newly planned areas such as suburbs or high-tech zones, and are not suitable for ground transportation in urban areas, making it difficult to popularize trams. . There are many low-floor bogies, such as Chinese patent CN101979266 "100% low-floor light rail vehicle independent wheel power bogie", its (1) frame: the frame si...
