Description

一种用于自动变速器的油泵排气机构及自动变速器和车辆 技术领域
本申请涉及汽车传动技术领域，尤其涉及一种用于自动变速器的油泵排气机构及自动变速器和车辆。
背景技术
变速器(又称变速箱)是汽车上的一个部件，分为手动变速器和自动变速器两种。手动变速器主要由齿轮和轴组成，通过不同的齿轮组合产生变速变矩；而自动变速器是由液力变扭器、行星齿轮和液压操纵系统组成，通过液力传递和齿轮组合的方式来达到变速变矩。变速器的主要功能为：一、改变传动比；二、在发动机旋转方向不变情况下，使汽车能倒退行驶；三、利用空挡，中断动力传递，以使发动机能够起动、怠速，并便于变速器换挡或进行动力输出。目前，随着汽车工业的发展，自动变速器已经成为发展趋势。自动变速器油泵作为自动变速器离合系统和变速箱内部各摩擦副润滑装置的动力源，是自动变速器的重要组成部分，是关系到汽车动力性、经济型和舒适性的关键零部件之一。自动变速器油泵对整车的油耗、性能和价格对整车的影响不可小视。
自动变速器油泵的工作原理是相啮合的油泵转子组件旋转，通过改变相啮合的转子与具有吸入端和排出端口的壳体形成的容积变化来吸入和排放流体。按照油泵转子的结构形式，自动变速器油泵分为外啮合齿轮泵和内啮合齿轮泵两种。由于外啮合齿轮泵存在流量脉动率高、噪音大、困油严重等缺点，为了改善变速器NVH(Noise、Vibration、Harshness，噪声、振动与声振粗糙度)性能，结构更紧凑，因此自动变速器多采用内啮合式电子油泵，它具有结构紧凑、自吸能力强、流量波动小、噪音低等优点。由于变速器暴露在车辆底部，当整车没有底护板防护时，车辆行驶至涉水路段或者路面水飞溅时，电子油泵存在进水风险，进而可能影响其正常运行。
因此，有必要提出一种用于自动变速器的油泵排气机构及自动变速器和车辆，以解决上述技术问题。
发明内容
本申请的目的在于提供一种用于自动变速器的油泵排气机构及自动变速器和车辆，通过在传感器插接组件上设置倾斜的排气孔，以避免车辆涉水时有水飞溅进入电子油泵，从而保证了在车辆涉水工况下油泵的正常运行。

进一步地，所述防水基膜通过粘结的方式固定于所述传感器插接组件的内部。
进一步地，所述接合面通过销孔定位于变速器壳体上，并通过螺栓与变速器壳体固定连接。
进一步地，所述油泵为内啮合齿轮泵，包括外齿齿轮、内齿齿轮、月牙形隔板和泵壳，所述外齿齿轮和所述内齿齿轮均设于所述泵壳内部的空腔内，所述外齿齿轮为主动齿轮，所述内齿齿轮为从动齿轮，所述月牙形 隔板将所述外齿齿轮和所述内齿齿轮隔开。
进一步地，所述油泵还包括进油口和出油口，所述进油口用于吸入液压油，所述出油口用于排出液压油。

2、本申请的用于自动变速器的油泵排气机构及自动变速器和车辆，在传感器插接组件内部孔口处设置防水基膜，在保证油泵工作产生的热量可以排出的同时，又可以避免涉水严重时外部有水强制倒灌进电子油泵中，在车辆涉水严重的行驶工况下，倾斜排气孔和防水基膜起到对电子油泵的双重保障作用。

相应地，本申请实施例还提供一种车辆，该车辆包括上述的自动变速器。
本申请的上述实施例，具有如下有益效果：
1、本申请的用于自动变速器的油泵排气机构及自动变速器和车辆，在传感器插接组件上设置排气孔，排气孔设置成相对于地面方向斜向上斜孔，一方面，能够保证油泵工作时产生的压力通过排气孔排除，另一方面，在行车处于涉水工况或者路面有水飞溅时，因为水珠的重力作用，自动变速器油泵不会出现主动“存水”现象，从而可以避免车辆涉水时有水或其他杂物飞溅进入电子油泵，进而保证了在车辆涉水工况下油泵的正常运行；
2、本申请的用于自动变速器的油泵排气机构及自动变速器和车辆，在传感器插接组件内部孔口处设置防水基膜，在保证油泵工作产生的热量可以排出的同时，又可以避免涉水严重时外部有水强制倒灌进电子油泵中，在车辆涉水严重的行驶工况下，倾斜排气孔和防水基膜起到对电子油泵的双重保障作用。
以上所述是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
