Problems solved by technology

However, the structure of the existing air conditioner torque limiter is mostly complicated, which increases the manufacturing cost of the air conditioner drive, and the maintenance after the protection device is damaged is also relatively inconvenient.
Although some drivers with overload protection have also appeared in the existing technology, most of them realize overload protection by disconnecting the reed in the driver, but the flying fragments when the reed is disconnected often damage other components, and then the tiny fragments It is also extremely difficult to completely remove, causing problems such as abnormal noise when the vehicle is running

Embodiment 1

[0027] Such as figure 1 , 2 , 8 and 9, an overload protection device for a torque driver, which includes a figure keyboard 1 and a group of connected arc reeds 2, one end of each arc reed 2 is provided with a snap-in gap 4, The other end is provided with a connecting part 2b that is connected and matched with the pulley, and the end where the snap-in notch 4 is located is not on the same level as the end where the connecting part 2b is located, so that the arc-shaped reed 2 has a Elasticity in direction. The spline key 1 is composed of a connection plate 1b and its connected spline sleeve 1e, and a central gasket 8 is also provided in the spline sleeve 1e, and the spline sleeve 1e forms a connection with the compressor .

[0028] The radian of the clamping notch 4 is the same as that of the arc-shaped reed 2, and it includes: a clamping hole 4a corresponding to the rivet 3, and a clamping gap 4b communicating with the outside is provided on one side of the clamping hole 4a....

Embodiment 2

[0035] Such as Figure 3-9 As shown, an overload protection device for a torque driver, it includes a figure keyboard 1, and a group of three arc-shaped reeds 2, each end of one end of the arc-shaped reed 2 is provided with a snap-in gap 4, and the other end of the The end portion is provided with a connecting portion 2b that is connected and matched with the pulley, and the arc-shaped reed 2 is connected to the pulley by passing a bolt not shown in the figure through the connecting hole 2c on the connecting portion 2b. The end where the locking notch 4 is located is not on the same level as the end where the connecting portion 2 b is located, so that the arc-shaped reed 2 has elasticity along the axial direction of the keypad 1 .

[0036] The spline key 1 includes a spline sleeve 1e, and a central gasket 8 is arranged inside the spline sleeve 1e, and the spline sleeve 1e forms a connection and fit with the compressor. One end of the spline sleeve 1e is connected to the splin...

Abstract

The invention provides an overload protection device of a torque driver. The overload protection device of the torque driver comprises a spline disc (1) and a group of arc-shaped reeds (2), wherein alocking notch (4) is formed in the end portion of one end of each arc-shaped reed (2) while a connecting portion (2b) connected to and matched with a belt wheel is arranged on the end portion of the other end; the device is characterized in that a group of mounting grooves (1g) are uniformly formed in the spline disc (1), a holding rack (2b) is arranged in each mounting groove (1b), the end portion of one end of each arc-shaped reed (2) is inserted into the corresponding holding rack (6), a pre-tightening plate (5) is arranged on each arc-shaped reed and a gasket (7) is arranged below each arc-shaped reed, and the pre-tightening plate (5), the locking notch (4), the gasket (7), the holding rack (6) and the spline disc (1) are fixedly connected together trough a rivet (3). The device provided by the invention is simple in structure, convenient to manufacture and low in cost, and a compressor stops working by isolating the reeds from dowels, so that an overload protection effect is exerted.

Description

Technical field: [0001] The invention relates to a driver for an automobile air conditioner, in particular to an overload protection device for a torque driver. Background technique: [0002] The automotive air conditioner driver ensures that the compressor stops working when the compressor reaches the rated torque value, which can effectively protect the service life of the device. However, most of the structures of the existing air conditioner torque limiters are relatively complicated in structure, which increases the manufacturing cost of the air conditioner driver, and the maintenance after the protection device is damaged is also relatively inconvenient. Although some drivers with overload protection have also appeared in the existing technology, most of them realize overload protection by disconnecting the reed in the driver, but the flying fragments when the reed is disconnected often damage other components, and then the tiny fragments It is also extremely difficul...
