Problems solved by technology
However, this form of belt tensioning device needs to pre-install the motor and the screw torque cannot be twisted in place. After the adjustment is completed, the motor must be kept still, and finally the screw is locked. The process is cumbersome; The tension is not as good as the initial state, and the belt is prone to slipping or loosening. The desired tension can only be obtained by pre-installing fine-tuning and keeping it still, which increases the assembly time and has the risk of failure after durability

The present disclosure relates to a REPS belt tensioning device and a vehicle. The belt tensioning device includes a motor, a lead screw, a pulley reduction mechanism, a small pulley connected with the output shaft of the motor, and a large belt connected with the lead screw. A pulley, and a belt sleeved on the small pulley and the large pulley, the casing is used to close the pulley deceleration mechanism, and the adjustment mechanism arranged between the small pulley and the large pulley, and the adjustment mechanism includes a set on the casing. The support shaft in the adjustment hole, the roller connected to the support shaft for abutting with the belt, and the adjustment member connected with the support shaft, the adjustment member drives the support shaft to move axially in the adjustment hole, and drives the roller along the approaching Or move away from the belt. The adjusting piece drives the support shaft to move outward in the axial direction, which can reduce the force exerted by the roller on the belt. The tension and tension adjustment are simple and quick to operate.
Description
technical field [0001] The present disclosure relates to the field of automobile steering, and in particular, to a REPS belt tensioner and a vehicle. Background technique [0002] Rack-assisted Electric Power Steering (REPS) provides assistance by driving the rack through a booster motor and a reduction mechanism to adjust the tension of the belt. However, this form of belt tensioning device requires a pre-installed motor and the torque of the screw cannot be twisted in place. After the adjustment, it is necessary to ensure that the motor does not move, and finally the screw is locked, which is a complicated process; and for vehicles that have been used for a long time, the belt is attenuated and tensioned. The tightening force is not as good as the initial state, and the belt is prone to slippage or looseness. The desired tension can only be obtained by pre-installing and fine-tuning to keep it still, which increases the assembly time and has the risk of failure after durab...
