Description

本発明は、ミキサ車において車体枠上に搭載されたミキサドラムを回転させるミキサドラム駆動装置に関するものである。   The present invention relates to a mixer drum driving device for rotating a mixer drum mounted on a vehicle body frame in a mixer vehicle.

従来、車体上にミキサドラムが回転自在に搭載され、このミキサドラムを駆動回路を通じて回転駆動させるようにしたミキサ車が提供されている。   2. Description of the Related Art Conventionally, a mixer vehicle is provided in which a mixer drum is rotatably mounted on a vehicle body, and the mixer drum is driven to rotate through a drive circuit.

そして、上記駆動回路では、車輌のエンジンを駆動源として油圧ポンプを駆動させてミキサドラムに連繋している油圧モータに圧油を供給することで、この油圧モータを駆動させてミキサドラムを回転させるようにしていた（例えば、特許文献１参照。）。
特開平１−２４９５３８号公報 In the above drive circuit, the hydraulic pump is driven using the vehicle engine as a drive source to supply pressure oil to the hydraulic motor connected to the mixer drum, thereby driving the hydraulic motor to rotate the mixer drum. (For example, refer to Patent Document 1).
JP-A-1-249538

しかしながら、上記従来のものでは、ミキサドラムの回転は車輌のエンジンの駆動が前提になっていることから、車輌のエンジンを停止させた状態ではミキサドラムを回転させることができなかった。従って、例えばエンジンを停止している時にミキサドラムを回転させる必要が生じた場合には、必ずエンジンを駆動させる必要があった。   However, in the above-described conventional apparatus, since the rotation of the mixer drum is premised on the driving of the vehicle engine, the mixer drum cannot be rotated when the vehicle engine is stopped. Therefore, for example, when it is necessary to rotate the mixer drum when the engine is stopped, the engine must be driven.

このため、例えば住宅地近辺でミキサドラムを回転させる場合には、エンジン音による騒音や、排気ガスの排気などによって周辺環境を阻害するという問題が生じていた。また、エンジンを駆動させるために燃料消費効率の低下を招くという問題があった。   For this reason, for example, when the mixer drum is rotated in the vicinity of a residential area, there has been a problem that the surrounding environment is disturbed by noise caused by engine noise, exhaust gas exhaust, and the like. In addition, there is a problem that the fuel consumption efficiency is lowered to drive the engine.

本発明は、上記問題点に鑑みてなされたもので、その目的とするところは、駆動回路に電動モータによって駆動する油圧ポンプを備えた補助駆動回路を併設することで、エンジンの駆動だけでなく電動モータの駆動によってもミキサドラムを回転させることができるミキサ車のミキサドラム駆動装置を提供することにある。   The present invention has been made in view of the above problems, and the object of the present invention is not only to drive the engine by providing an auxiliary drive circuit including a hydraulic pump driven by an electric motor in the drive circuit. An object of the present invention is to provide a mixer drum driving device for a mixer vehicle that can rotate a mixer drum even by driving an electric motor.

上記の目的を達成するため、請求項１に係る発明のミキサ車のミキサドラム駆動装置は、車体上に回転自在に搭載されたミキサドラムと、車輌のエンジンを駆動源として駆動する油圧モータによりミキサドラムを回転駆動させる駆動回路とを備えたミキサ車のミキサドラム駆動装置において、前記駆動回路には、電動モータによって駆動する油圧ポンプにより切換制御弁を介して前記油圧モータを駆動する補助駆動回路が併設されたものである。   In order to achieve the above object, a mixer drum driving device for a mixer vehicle according to a first aspect of the present invention rotates a mixer drum by a mixer drum that is rotatably mounted on a vehicle body and a hydraulic motor that drives a vehicle engine as a drive source. In the mixer drum driving device of a mixer vehicle provided with a driving circuit to be driven, the driving circuit is provided with an auxiliary driving circuit for driving the hydraulic motor via a switching control valve by a hydraulic pump driven by an electric motor It is.

本発明によれば、車輌のエンジンを停止した状態でも電動モータの駆動によってミキサドラムを回転させることができ、これにより車輌のエンジンの駆動に起因するエンジン音による騒音や、排気ガスの排気などの発生を無くすことで、周辺環境に与える悪影響を防止することができる。   According to the present invention, the mixer drum can be rotated by driving the electric motor even when the vehicle engine is stopped, thereby generating noise due to engine noise caused by driving the vehicle engine, exhaust gas exhaust, etc. By eliminating this, adverse effects on the surrounding environment can be prevented.

以下、本発明の実施の形態について図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本発明に係るミキサ車の駆動系となる油圧回路を示している。   FIG. 1 shows a hydraulic circuit serving as a drive system for a mixer vehicle according to the present invention.

図１において、１はミキサ車の車体上に回転自在に搭載されたミキサドラムで、このミキサドラム１は駆動回路２によって正逆方向に回転駆動するように構成されている。   In FIG. 1, reference numeral 1 denotes a mixer drum that is rotatably mounted on the body of a mixer vehicle. The mixer drum 1 is configured to be driven to rotate in forward and reverse directions by a drive circuit 2.

駆動回路２は、車輌に搭載された従来周知な回路であって、基本的には可逆可変容量油圧ポンプ（以下、単にポンプという）Ｐを備えたポンプユニット３と、油圧モータＭを備えたモータユニット４とから構成されている。   The drive circuit 2 is a conventionally known circuit mounted on a vehicle, and basically a pump unit 3 having a reversible variable displacement hydraulic pump (hereinafter simply referred to as a pump) P, and a motor having a hydraulic motor M. The unit 4 is configured.

ポンプＰは、車輌のエンジン（図示せず）によって駆動し、ポンプユニット３に組み込まれた定速制御弁３１によって吐出量などが制御されるようになされている。このポンプＰは上記モータユニット４の油圧モータＭに油路５１、５２よって連通されており、オイルタンクＴを通じてポンプＰから油圧モータＭに供給する圧油の供給経路を切換えることで、油圧モータＭを正逆方向に回転させるようにしている。   The pump P is driven by a vehicle engine (not shown), and the discharge amount and the like are controlled by a constant speed control valve 31 incorporated in the pump unit 3. The pump P communicates with the hydraulic motor M of the motor unit 4 through oil paths 51 and 52, and the hydraulic motor M is switched by switching the supply path of the pressure oil supplied from the pump P to the hydraulic motor M through the oil tank T. Is rotated in the forward and reverse directions.

上記油圧モータＭは、上記ミキサドラム１に連繋されており、この油圧モータＭの駆動によってミキサドラム１を正逆方向に回転させるように構成している。   The hydraulic motor M is connected to the mixer drum 1 and is configured to rotate the mixer drum 1 in forward and reverse directions by driving the hydraulic motor M.

そして、このように構成された従来周知の駆動回路２に本発明の主要部を構成する補助駆動回路６が併設されている。   An auxiliary drive circuit 6 constituting the main part of the present invention is provided in addition to the conventionally known drive circuit 2 configured as described above.

補助駆動回路６は、電動モータ６１によって駆動する油圧ポンプ６２と、切換制御弁６３とを備えている。   The auxiliary drive circuit 6 includes a hydraulic pump 62 that is driven by an electric motor 61 and a switching control valve 63.

油圧ポンプ６２は、油路６４によって吸込側がオイルタンクＴに連通されるとともに吐出側が切換制御弁６３に連通されている。   The hydraulic pump 62 is connected to the oil tank T on the suction side by an oil passage 64 and to the switching control valve 63 on the discharge side.

切換制御弁６３は、ソレノイドの励磁・消磁によって切換可能な電磁式３位置切換弁であって、チェック弁６６を備えた油路６５によってオイルタンクＴに連通され、また油路６７、６８を通じて前記油路５１、５２に連通されている。   The switching control valve 63 is an electromagnetic three-position switching valve that can be switched by excitation and demagnetization of a solenoid, and is communicated with an oil tank T by an oil passage 65 having a check valve 66, and also through the oil passages 67 and 68. The oil passages 51 and 52 communicate with each other.

そして、このように構成された補助駆動回路６によってミキサドラム１を回転させる場合には、まず、車輌のエンジンを停止してミキサドラム１が停止している状態で、電動モータ６１を電源に接続して当該電動モータ６１を駆動させる。これにより油圧ポンプ６２が作動して圧油を切換制御弁６３を通じて油路５１もしくは油路５２に供給して前記油圧モータＭを回転駆動させることで、ミキサドラム１を回転させることができる。この場合、切換制御弁６３を中立位置から左右位置に切換操作することで、ミキサドラム１を正逆いずれかの方向に回転させるようにしている。   When the mixer drum 1 is rotated by the auxiliary drive circuit 6 configured as described above, first, the electric motor 61 is connected to the power source while the engine of the vehicle is stopped and the mixer drum 1 is stopped. The electric motor 61 is driven. As a result, the hydraulic pump 62 is operated, pressure oil is supplied to the oil passage 51 or the oil passage 52 through the switching control valve 63, and the hydraulic motor M is driven to rotate, whereby the mixer drum 1 can be rotated. In this case, the mixer drum 1 is rotated in either the forward or reverse direction by switching the switching control valve 63 from the neutral position to the left-right position.

このように車輌のエンジンを停止した状態でも電動モータ６１の駆動によってミキサドラム１を回転させることができるので、例えばエンジンを停止している時にミキサドラムを回転させる必要が生じた場合でもこれに対応することができるようになる。   Thus, even when the engine of the vehicle is stopped, the mixer drum 1 can be rotated by driving the electric motor 61. Therefore, for example, when it is necessary to rotate the mixer drum when the engine is stopped, this should be handled. Will be able to.

また、車輌のエンジンの駆動に起因するエンジン音による騒音や、排気ガスの排気などの発生を無くすことで、周辺の環境を阻害することなく、また無駄な燃料消費を抑えて環境にもやさしい。   Further, by eliminating the noise caused by engine noise caused by the driving of the engine of the vehicle and the generation of exhaust gas, etc., the surrounding environment is not hindered, and wasteful fuel consumption is suppressed, which is friendly to the environment.
