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 low-floor bogie with rubber tires, which includes an independent wheel set, a frame, a motor gearbox transmission device, a secondary suspension device, and a traction device. The frame consists of two side beams, two cross beams and two end beams Composition; the independent wheel set includes four rubber tires and four reversing transmission gearboxes, each rubber tire is equipped with a reversing transmission gearbox; the motor gearbox transmission device is installed in the middle of the frame side beam, including The motor and the gearbox, the motor and the gearbox are designed as one type, the motor is arranged horizontally, the gearbox is arranged vertically and the gearbox outputs to both ends at the same time; the transmission device of the motor gearbox is connected to the motor gearbox through two universal joints Two reversing drive gearboxes on the same side of the transmission. Therefore, the present invention realizes that the rail vehicle can run on a non-track road surface, and realizes that the vehicle equipped with the bogie has a completely 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...
