Description

一种通道式离合器压盘A channel type clutch pressure plate

技术领域 technical field

本实用新型属于汽车配件技术领域,涉及一种离合器,具体是一种通道式离合器压盘。 The utility model belongs to the technical field of auto parts and relates to a clutch, in particular to a channel-type clutch pressure plate.

背景技术 Background technique

压盘是一个环形金属圆盘,常见为实心体结构,常用于汽车离合器之中。汽车离合器压盘在重载荷起步和上坡加速等过程中,易出现离合器打滑、烧片故障。故障主要原因在于,在离合器接合过程中离合器摩擦片与压盘间产生滑动摩擦,摩擦功将转化为热能,使压盘温度升高、扭矩传递能力下降,最终导致离合器打滑、烧片故障。 The pressure plate is an annular metal disc, which is usually a solid structure and is often used in automobile clutches. The clutch pressure plate of an automobile is prone to clutch slipping and burning disc failures during heavy-load starting and uphill acceleration. The main reason for the failure is that during the clutch engagement process, sliding friction occurs between the clutch friction plate and the pressure plate, and the friction work will be converted into heat energy, which will increase the temperature of the pressure plate and reduce the torque transmission capacity, which will eventually lead to clutch slipping and burning plate failure.

为解决这个问题,公开号为CN203756784U的中国专利“压盘”公开了这样一种结构:一种压盘,包括环形本体,在所述环形本体的中心位置设有中心孔,所述环形本体包括内边缘和外边缘,所述外边缘上设有若干散热通孔,所述内边缘上设有导流槽,所述散热通孔与所述导流槽导通,相邻两散热通孔之间设有加强筋,散热通孔相对于加强筋的另一侧上设有散热槽,所述散热槽位于相邻两散热通孔之间且与散热通孔导通。这种结构通过散热槽、散热通孔、导流槽的相互导通实现加强散热,并保证压盘的强度和刚度。但在该专利中,所设计的导流槽是沿径向从散热通孔通向压盘内边缘,使得热气流向压盘中心汇聚,不利于压盘快速散热。 In order to solve this problem, the Chinese patent "pressure plate" with publication number CN203756784U discloses such a structure: a pressure plate includes an annular body, a central hole is arranged at the center of the annular body, and the annular body includes The inner edge and the outer edge, the outer edge is provided with a number of heat dissipation through holes, the inner edge is provided with a diversion groove, the heat dissipation through hole is connected with the diversion groove, and the gap between the two adjacent heat dissipation through holes is Reinforcing ribs are arranged between them, and a heat dissipation groove is provided on the other side of the heat dissipation through hole relative to the reinforcement rib, and the heat dissipation groove is located between two adjacent heat dissipation through holes and communicates with the heat dissipation through hole. This structure realizes enhanced heat dissipation through the interconnection of heat dissipation grooves, heat dissipation through holes, and flow guide grooves, and ensures the strength and rigidity of the pressure plate. However, in this patent, the designed guide groove is radially from the heat dissipation through hole to the inner edge of the pressure plate, so that the hot air flows to the center of the pressure plate to converge, which is not conducive to the rapid heat dissipation of the pressure plate.

因而现有的离合器压盘散热能力有限,不能快速散热、降低压盘温升,最终导致离合器打滑、烧片故障。 Therefore, the heat dissipation capacity of the existing clutch pressure plate is limited, and it cannot quickly dissipate heat and reduce the temperature rise of the pressure plate, which eventually leads to clutch slipping and burnt plate failure.

下面结合附图和实施例对本实用新型内容作进一步的阐述,但不是对本实用新型的限定。 The content of the utility model will be further elaborated below in conjunction with the accompanying drawings and embodiments, but the utility model is not limited.

实施例: Example:

参照图1-图3,一种通道式离合器压盘,包括环形本体1,所述环形本体1内部设有径向散热通道2、周向散热通道3,所述环形本体1端面设有贯通环形本体1的轴向散热通孔4; Referring to Figures 1-3, a channel-type clutch pressure plate includes an annular body 1, a radial heat dissipation channel 2 and a circumferential heat dissipation channel 3 are provided inside the annular body 1, and a through-ring ring is provided on the end surface of the annular body 1. The axial cooling through hole 4 of the body 1;

所述散热通孔4、径向散热通道2、周向散热通道3相互连通。 The heat dissipation through holes 4 , the radial heat dissipation channels 2 and the circumferential heat dissipation channels 3 communicate with each other.

所述径向散热通道2为弧形通道,其外端延伸至环形本体1的外边缘11,内端延伸至环形本体1的内边缘12。 The radial cooling channel 2 is an arc-shaped channel, its outer end extends to the outer edge 11 of the ring body 1 , and its inner end extends to the inner edge 12 of the ring body 1 .

本实施例径向散热通道2为右螺旋弧形通道。弧形通道能增加对流换热面积,加快压盘散热;右螺旋方向能与压盘高速旋转方向匹配,充分利用压盘高速旋转产生的离心力作用,加快气流速度,加快压盘散热。 In this embodiment, the radial heat dissipation channel 2 is a right spiral arc channel. The arc-shaped channel can increase the convective heat transfer area and accelerate the heat dissipation of the pressure plate; the right-hand helical direction can match the high-speed rotation direction of the pressure plate, and make full use of the centrifugal force generated by the high-speed rotation of the pressure plate to speed up the airflow and speed up the heat dissipation of the pressure plate.

所述径向散热通道2的数量为20-28个,本实施例的数量为24个。 The number of radial cooling channels 2 is 20-28, and the number in this embodiment is 24.

所述周向散热通道3的数量为1-3个,本实施例的数量为2个。 The number of the circumferential cooling channels 3 is 1-3, and the number in this embodiment is 2.

与径向散热通道相通的散热通孔41其数量为12-48个,本实施例的数量为30个。 The number of heat dissipation through holes 41 communicating with the radial heat dissipation passages is 12-48, and the number in this embodiment is 30.

与周向通风通道相通的散热通孔42其数量为18-36个,本实施例的数量为27个。 The number of heat dissipation through holes 42 communicating with the circumferential ventilation channel is 18-36, and the number of this embodiment is 27.

所述的散热通孔4在环形本体1上交错排列。散热通孔4交错排列,使得在保障压盘端面强度的基础上,端面散热通孔能与内部径向散热通道、周向散热通道较均匀地联通。 The heat dissipation through holes 4 are arranged in a staggered manner on the annular body 1 .

The forced convection heat transfer of the heat dissipation channel and the centrifugal force of the pressure plate rotation accelerate the airflow speed, and a large amount of airflow quickly flows from the inner edge 12 of the body to the outer edge 11 of the body and then radiates into the ambient air, thereby enhancing the heat dissipation of the pressure plate and reducing the temperature of the end surface of the pressure plate Lift.

与常规同尺寸压盘相比较,经实测本压盘重量减轻约2~3公斤;能明显降低压盘摩擦时的温升;改善离合器压盘打滑、烧片故障,提高离合器使用寿命。 Compared with the conventional pressure plate of the same size, the measured weight of this pressure plate is about 2~3 kg; it can significantly reduce the temperature rise of the pressure plate during friction; it can improve the clutch pressure plate slipping and burning failure, and increase the service life of the clutch.
