Abstract
The utility model relates to a hydraulic retarder with a novel speed sensor. The hydraulic retarder comprises a double insulated wire and a plug-in connection device and a speed sensor, which are connected to the two ends of the double insulated wire respectively, wherein the speed sensor comprises a speed sensor housing with one closed end, a magnet arranged at the closed end of the inner cavity of the speed sensor, a combined coil formed by winding an enameled wire on a coil frame, an iron core arranged in the center of the coil frame, a connection magnet and a wire clamp which are connected with the double insulated wire, an insulated lead wire electrically connected between the combined coil and the wire clamp, and a silica gel filler integrally injected in the inner cavity of the speed sensor housing. With the structure, the speed sensor of the hydraulic retarder has the characteristics of good sealing property and capability of preventing the silica gel from being loosened.
Description
Technical field
The utility model relates to the brake device for car technical field, refers in particular to a kind of hydrodynamic retarder that adopts novel speed sensor.
Background technology
At present, hydrodynamic retarder is as a kind of complemental brake system, and domestic only have use on the senior palace car of minority, and in developed country, be widely used in all kinds of high speeds, heavy-duty vehicle.Hydrodynamic retarder is made up of parts such as stator impeller, rotor wheel, speed sensors.Speed sensor is made up of parts such as shell and plugs at present, CN200810068211.3 discloses a kind of " magnetoelectricity type passive velocity transducer and manufacturing process thereof ", its structure as shown in Figure 1, this speed retarder shell is the penetrating tubular constructions in front and back, the shell of this structure is when canned silica gel, can not play good sealing and prevent the effect that silica gel is loosening, therefore limit the widespread use of existing speed sensor.
Summary of the invention
This later-model purpose is exactly the hydrodynamic retarder that provides a kind of good airproof performance at the deficiencies in the prior art part, can prevent the novel speed sensor of employing that silica gel is loosening.
For achieving the above object, this later-model technical scheme is: a kind of hydrodynamic retarder that adopts novel speed sensor, include: two insulated wires and the connector and the speed sensor that are connected to two insulated wire two ends, described speed sensor includes an end osed top speed sensor shell, place the magnet of speed sensor inner chamber closed end, enamel wire is wound on the built-up coil on the coil rack, place the iron core at coil rack center, be connected shell mica and cableties with two insulated wire bonded assemblys, and being connected the insulator pin that is electrically connected between built-up coil and the cableties, also whole embedding has filling gel in the inner chamber of speed sensor shell.
Described speed sensor shell is one-body molded to be the housing that end sealing other end opening has inner chamber.
Have some locking groove or threads groove of being used on the inner cylinder face of described speed sensor shell.
Have on the described speed sensor shell and be convenient to direct leak free connection end face.
Described connector is by connector terminal, the Outside Dimensions waterproof plug greater than the connector terminal, and the locking card between waterproof plug and the connector terminal is formed.
Described pair of insulated wire is coated with heat-shrinkable T bush.
After adopting said structure, the utility model compared with prior art has following advantage:
1. because the speed sensor cover top portion is an one, increased the leak tightness of speed sensor, can prevent effectively that hydrodynamic retarder from oozing out from the speed sensor internal with oil.
2. owing to have some channel form or screw retention on the speed sensor shell inner cylinder face, can prevent the loosening of two component silica gel effectively and come off.
3. be directly used in the leak free end face owing to being installed with on the speed sensor shell, increased the comfort feature of installing widely.
Description of drawings
Fig. 1 is the hydraulic speed buffer structure scheme drawing that adopts existing speed sensor.
Fig. 2 is the structural representation that the utility model adopts the hydrodynamic retarder of novel speed sensor.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the hydraulic speed buffer structure scheme drawing that adopts existing speed sensor, wherein, this speed retarder shell 31 is the penetrating tubular constructions in front and back, and the shell of this structure can not play good sealing and prevent the effect that silica gel is loosening when canned silica gel 38.
Fig. 2 is the structural representation that the utility model adopts the hydrodynamic retarder of novel speed sensor, this novel including: two insulated wires 12 and the connector and the speed sensor that are connected to two insulated wire 12 two ends, described speed sensor includes an end osed top speed sensor shell 31, place the magnet 32 of speed sensor inner chamber closed end, enamel wire is wound on the built-up coil 35 on the coil rack 34, place the iron core 36 at coil rack 34 centers, be connected shell mica 33 and cableties 30 with two insulated wire 12 bonded assemblys, and being connected the insulator pin 331 that is electrically connected between built-up coil 35 and the cableties 30, also whole embedding has filling gel 38 in the inner chamber of speed sensor shell 31.Silica gel 38 is two component silica gel.Described speed sensor shell 31 is one-body molded to be the housing that end sealing other end opening has inner chamber.Have some locking groove or threads groove 311 of being used on the inner cylinder face of described speed sensor shell 31.Have on the described speed sensor shell 31 and be convenient to direct leak free connection end face 312.Described pair of insulated wire 12 is coated with heat-shrinkable T bush 11.Two insulated wires 12 of described heat-shrinkable T bush 11 suits are the Teflon electric wire with the insulator pin 331 of the interior cableties 30 of shell.
Greater than the waterproof plug 22 of connector terminal 21 and one-body molded between waterproof plug 22 and connector terminal 21 and Outside Dimensions is all formed less than the locking card 23 of waterproof plug 22 and connector terminal 21, locking card 23 is 21 formation tapering transitions from waterproof plug 22 to the connector terminal by the connector terminal 21 that is connected in two insulated wire 12 ends in the heat-shrinkable T bush 11, Outside Dimensions for described connector 2.
The above only is the preferred embodiment of the utility model patent, and all equalizations of being done according to the utility model patent claimed range change and modify, and all should belong to the covering scope of the utility model Patent right requirement.
