Description

Engine gear train protective cover and vehicle with same

Technical Field

The invention relates to the technical field of vehicle protection accessory design, in particular to an engine gear train protective cover and a vehicle with the same.

Background

Currently, most of engine wheel trains (a system consisting of pulleys of a crank pulley at the front end of an engine, an air conditioner compressor, a generator, a water pump and the like) are directly exposed outside the engine. When the vehicle wades, accumulated water on the road surface easily washes the wheel system, so that a water film is generated between the belt and the belt wheel, and the wheel system is slipped. In particular, in a gear train system using a 48V motor, the motor can generate torque (negative torque) opposite to that of a belt pulley, and if the belt and the belt pulley slip, the motor is easy to reverse, so that faults are caused. In view of the above problems, current solutions generally circumvent failure by increasing the train tension and adjusting the motor torque control strategy. However, excessive tension increases the axle load of each pulley and the load of the belt, resulting in a reduction in the reliability of the train structure; adjusting the control strategy of the motor is also typically done at the expense of performance. Both of the above approaches reduce the risk of failure from the side and do not essentially solve the problem of slip caused by water entering the wheel train.

In view of the above problems in the prior art, no effective solution has been proposed at present.

Referring to fig. 1-5, an engine train wheel guard is provided according to an embodiment of the present application.

The engine train protection casing includes: a driving part 10, a first shielding fan blade 20 and a second shielding fan blade 30. The driving section 10 has an output shaft 11. The first shutter blade 20 is connected to the output shaft 11. The second shielding fan blades 30 are multiple. The plurality of second shielding blades 30 are rotatably connected to the output shaft 11. One of the plurality of second shielding blades 30 is connected to the first shielding blade 20. Two adjacent second shielding blades 30 are connected through a connecting structure 40. The first shielding fan blade 20 and the plurality of second shielding fan blades 30 are disposed at intervals along the axial direction of the output shaft 11. Wherein the first shielding fan blade 20 and the plurality of second shielding fan blades 30 have an open position and a folded position. When the first shielding fan blade 20 and the plurality of second shielding fan blades 30 are located at the open position, the first shielding fan blade 20 and at least part of the second shielding fan blades 30 are sequentially unfolded to form a protection fan surface. When the first shielding fan blade 20 and the plurality of second shielding fan blades 30 are located at the folding position, the projection of the first shielding fan blade 20 along the axis direction of the output shaft 11 coincides with the projection of the plurality of second shielding fan blades 30 along the axis direction of the output shaft 11. As shown in fig. 1, the engine gear train protective cover is in an open position. As shown in fig. 2, the engine train protective cover is in a folded position.

As shown in fig. 1, when the first shielding fan blade 20 and the plurality of second shielding fan blades 30 are located at the open position, the projection of the first shielding fan blade 20 along the axis direction of the output shaft 11 and the projection of at least part of the second shielding fan blades 30 along the axis direction of the output shaft 11 are offset, so that the first shielding fan blade 20 and the plurality of second shielding fan blades 30 form a protection fan surface.

By means of the technical scheme, the first shielding fan blades 20 and the plurality of second shielding fan blades 30 are switched between the open position and the folding position, so that the engine gear train protective cover can effectively prevent accumulated water from carrying out a gear train when a vehicle wades, the problem of gear train slipping is solved, and meanwhile, the heat dissipation performance of the engine gear train protective cover is considered. The shielding area of the engine gear train protective cover on the gear train structure is variable, and the influence on the gear train transmission is reduced to the greatest extent while the gear train is protected from being invaded by accumulated water. By adopting the technical scheme, the problem that the engine wheel train in the prior art is easy to slip is effectively solved.

Further, one of the plurality of second shielding blades 30, which is close to the first shielding blade 20, is connected to the first shielding blade 20 through a connection structure 40. The connection structure 40 includes: the tie rod 41 is connected. The two ends of the connecting pull rod 41 are respectively connected with the first shielding fan blade 20 and the second shielding fan blade 30, or the two ends of the connecting pull rod 41 are respectively connected with the two adjacent second shielding fan blades 30. The second shielding fan blade 30 is provided with a guide groove 42 along the radial direction of the output shaft 11, and at least one end of each connecting pull rod 41 is located in the guide groove 42. The adjacent second shielding fan blades 30 can be driven in a time delay manner by connecting the pull rod 41 with the guide groove 42.

Specifically, after the driving portion 10 drives the first shielding fan blade 20 to rotate by a preset angle, the second shielding fan blade 30 connected with the first shielding fan blade 20 can be driven to rotate, so that the rotating second shielding fan blade 30 continues to drive the adjacent second shielding fan blade 30 to rotate through the connecting pull rod 41. The driving unit 10 is preferably a servo motor. The arrangement makes the protection area of the engine wheel train protective cover variable, and the unfolding area realizes a variable form by controlling and adjusting the rotation angle of each fan blade through the servo motor. The first shielding fan blade 20 and the second shielding fan blades 30 may form a moving structure similar to a folding fan. The working state control of the protective cover can be realized by adopting one driving part 10, and the protective cover has simple structure and low cost.

The plurality of second shielding blades 30 are in clearance fit with the output shaft 11. The output shaft 11 is provided with a plurality of bearing sleeves, and each second shielding fan blade 30 is rotatably connected with the output shaft 11 through the bearing sleeve. By adopting the technical scheme of the embodiment, the second shielding fan blade 30 and the output shaft 11 can realize idle running.

In a preferred embodiment, the number of first shielding blades 20 is one, and the number of second shielding blades 30 is two. The first blocking fan blade 20 includes a first fan blade. The two second shielding blades 30 are respectively a second blade and a third blade. The first fan blade is fixedly connected with the servo electrode and rotates along with the servo motor. The second fan blade and the third fan blade are sleeved on the servo motor shaft through clearance fit or a bearing, but do not rotate along with the servo motor. The first fan blade is connected with the second fan blade (similar to a folding fan) through the connecting structure, and when the first fan blade rotates to a certain angle, the second fan blade can be driven to rotate together, the area of the protective cover is further enlarged, and the number of the fan blades can be selected according to actual requirements.

Further, the first shielding fan blade 20 and the second shielding fan blades 30 are provided with flanges 50 at sides away from the output shaft 11. The flange 50 extends in the axial direction of the output shaft 11. The flange 50 can further improve the protection effect of shielding the fan blades, and prevent accumulated water from splashing into the wheel train structure due to impact.

The engine train protective cover further comprises a motor controller, and the motor controller can control the driving part 10 to start when receiving a first preset signal sent by the water quantity sensor or a second preset signal sent by the rotating speed sensor. The arrangement can improve the response speed of the engine gear train protective cover, and realize timely work, and prevent the engine gear train protective cover from affecting the heat dissipation of the gear train structure. That is, when the wheel train wades, accumulated water can splash into the cabin, and when the water quantity sensor detects that the water quantity reaches the limit value or the rotating speed sensor detects that the rotating speed is abnormal (slipping), the motor control unit controls the servo motor to open the wheel train protective cover, and the opening area is determined by the control unit according to a control strategy. When the water quantity is reduced and the slip disappears, the area of the wheel train protective cover is reduced until the wheel train protective cover is closed. The control strategy may be adjusted according to vehicle demands to adapt to different vehicle demands.

The engine train cover is provided outside at least one of the crank pulley 60, the generator 70, and the air conditioner compressor pulley 80 of the engine train.

In an alternative embodiment, both the first and

second shielding blades

20, 30 are detachably connected to the drive shaft, such that the blades may be individually replaced after damage without affecting overall serviceability.

The first shielding fan blade 20 and the second shielding fan blade 30 are made of at least one of metal, plastic and rubber. The metal material can effectively improve the structural strength of the shielding fan blade, so that the shielding fan blade has excellent service life. The plastic material can effectively reduce the cost. The rubber material is effective in corrosion and shock resistance.

Further, a storage space is formed between the first shielding fan blade 20 and the output shaft 11, and when the first shielding fan blade 20 and the plurality of second shielding fan blades 30 are located at the folding position, the plurality of second shielding fan blades 30 are located in the storage space. The arrangement can ensure that the engine gear train protective cover has smaller occupied space and prevent the engine gear train protective cover from influencing the arrangement of the gear train structure.

According to another embodiment of the present invention, there is provided a vehicle including an engine train protective cover, the engine train protective cover being the engine train protective cover described above.

From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: the engine gear train protective cover can effectively protect the engine gear train and prevent accumulated water from entering between the belt wheel and the belt when the vehicle wades into water. The engine gear train protective cover starts from the essential cause of gear train slipping, and the gear train reliability is effectively improved through the arrangement of the protective cover. The engine gear train protective cover adopts a variable area form, is only opened when passing through a ponding road surface, and adjusts the opening degree according to the water quantity, so that the gear train is effectively protected, and the influence on the gear train is reduced to the minimum (the gear train protective cover affects heat dissipation or causes foreign matter accumulation).

Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "over" other devices or structures would then be oriented "below" or "beneath" the other devices or structures. Thus, the exemplary term "above … …" may include both orientations of "above … …" and "below … …". The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
