Embodiment
[0022] Embodiment: a kind of front and rear wheel drive switchable automobile steering device, such as figure 1 , 3 shown. The device comprises a turntable 1 rotatably arranged on the ground 2 . An annular groove 11 is dug on the ground 2 below the turntable and coaxial with the turntable 1 . The top of the ground inside the annular groove 11 is provided with a planar thrust bearing 10 that supports and rotates the turntable, and there are steps on the ground outside the annular groove that adapt to the thickness of the turntable, so that the upper surface of the turntable is flush with the ground. Balls 12 are arranged between the edge of the lower surface of the turntable and the ground for auxiliary support and rotation.
[0023] Such as figure 1 As shown, four pairs of rollers 3 are arranged at intervals of 90 degrees along the circumference of the turntable, and each pair of rollers 3 includes an inner roller 4 near the center of the turntable and an outer roller 5 ne...

The invention relates to a front / rear wheel driving-switchable vehicle steering device, and solves the vehicle turning problem in a narrow space. The device comprises a turntable rotationally mounted on the ground, wherein multiple sets of pair rollers for bearing vehicle wheels are evenly distributed on the turntable in the peripheral direction; the pair rollers near the center of the turntable are inner rollers, and the pair rollers near the edge of the turntable are outer rollers; corresponding locking devices are arranged on the inner rollers and the outer rollers; worm rods parallel to the pair rollers are respectively arranged below the pair rollers; the outer rollers are in forward transmission connection with one ends of the worm rods through clutches; the inner rollers are in reverse transmission connection with the other ends of the worm rods through clutches; worm wheels are correspondingly arranged at the outer sides of the worm rods; rotating gears are connected below the worm wheels through ratchet wheels; inner toothed rings engaged to the rotating gears are fixed on the ground; and the inner toothed rings are coaxially arranged with the turntable. The device finishes the fixed steering by the vehicle power, and realizes the vehicle steering switchover of front-wheel driving and rear-wheel driving.
Description
technical field [0001] The invention relates to an automobile steering assist device, in particular to an automobile steering device with switchable front and rear wheel drives. Background technique [0002] With the development of society and the popularization of private cars, the per capita car ownership has continued to rise, causing car parking spaces to become more and more tense. For places where parking is concentrated, such as parking lots, parking spaces must be provided at the corners and ends of each parking lot. There is room for cars to turn and turn around, which virtually reduces the parking utilization of the space. And for some narrow and narrow spaces, it is difficult for the car to turn and turn around, and it needs to move back and forth many times. For some new drivers, it may even cause the car to get stuck in the corner and cannot move. Contents of the invention [0003] The purpose of the present invention is to provide a car that utilizes the pow...
